Returning an array without assign to a variable

Question

Is there any way in java to return a new array without assigning it first to a variable? Here is an example:

public class Data {     private int a;     private int b;     private int c;     private int d;     public int[] getData() {         int[] data = { a, b, c, d };         return data;     } } 

I want to do something like this, but doesn't work:

public int[] getData() {     return {a, b, c, d}; } 

Answer 1

You still need to create the array, even if you do not assign it to a variable. Try this:

public int[] getData() {     return new int[] {a,b,c,d}; } 

Your code sample did not work because the compiler, for one thing, still needs to know what type you are attempting to create via static initialization {}.

Answer 2

You been to construct the object that the function is returning, the following should solve your issue.

public int[] getData() {     return new int[]{a,b,c,d}; } 

hope this helps
